摘要(Abstract)：

目的明确可溶性生长刺激表达基因2蛋白(soluble growth STimulation expressed gene2,sST2)对急性心肌梗死(acute myocardial infarction,AMI)后行经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)患者主要不良心血管事件(major adverse cardiovascular events,MACE)的预测价值。方法入选2015年1月至2016年5月入住兰州大学第一医院心脏中心的初发AMI患者148例,收集患者术前血清sST2水平及其他临床资料,并于PCI术后随访6~12个月,记录随访结果。结果(1)根据是否发生MACE,MACE组(23例)血清sST2水平明显高于非MACE组(125例)[(44.50±5.32)ng/ml比(23.59±1.15)ng/ml,P=0.001],差异有统计学意义。(2)血清sST2水平与体重指数(r=0.190,P=0.008)、高血压病(r=0.148,P=0.034)、三酰甘油(r=0.212,P=0.003)、中性粒细胞百分比(r=0.324,P<0.001)、谷丙转氨酶(r=0.152,P=0.031)、左心室收缩末期容积(r=0.195,P=0.018)及左心室射血分数(r=-0.275,P=0.001)等因素相关。(3)经双变量相关分析可知:血清sST2与MACE、Ⅲ型前胶原氨基端肽呈正相关,与氨基末端B型脑钠肽前体(N terminalprobrain natriuretic peptide,NT-proBNP)无相关性。(4)预测PCI术后MACE发生的ROC曲线。sST2+NT-proBNP联合曲线下面积明显大于sST2(0.820比0.787,P=0.045),sST2曲线下面积明显大于NF-proBNP(0.787比0.690,P=0.030)。(5)血清sST2水平≤29 ng/ml患者PCI术后6个月的生存率高于其sST2水平>29 ng/ml患者(100%比95.5%,P=0.029)。结论 sST2受多种因素影响,与NT-proBNP联合可提高对PCI术后MACE的预测价值,且患者sST2水平越高PCI术后6个月的死亡率越高。
